ICE-CREAM FREEZER.

SPECIFICATION forming part of Letters Patent No. 239,212, dated March 22, 1881.

Application filed February 17, 1881. (N0 model.)

To all whom t't may concern.-

Be it known that I, ANTONIUS G. ALBRECHT, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Ice-Cream Freezers,

In the accompanying drawings, Figure 1 is a vertical section of an ice-cream freezer with my improvements; Fig. 2, a sectional plan on the line 1 2, part of the cover of the can being removed to show the scraper Fig. 3, an inverted plan view of the cross-bar; Fig. 4, a transverse section on the line3 4, Fig. 3 5 Fig. 5, a vertical section of the cover of the can Fig. 6, a perspective view of the upper portion of the freezer, part of the crossbar being cut away to show the gearing; and Figs. 7 and 8, perspective views, showing the manner of connecting the wooden scraper to the arms of the dasher. The outer vessel, A, of the freezer, as shown in the present instance, is made of wood, but may be of sheet-iron galvanized, and to the top of this vessel is adapted the detachable crossbar B in the following manner: This cross-bar, which is made of cast-iron, has at one end a hook, a,which can, on raising the opposite end of the cross-bar, be introduced into a slot in a cleat, 12, secured to the outer vessel, said opposite end of the cross-bar having an opening, 61, for admitting the upper end, e, of the plate D, which is secured to the said outer vessel, A. When the cross-bar is in place it may be readily secured by a turn-buckle, E, which is pivoted to the bar, and on which is a segmental inclined plane, f, so that on moving the turnbuckle in thedirection of the arrow, Fig. 6, the inclined plane, bearing against the under side of a shoulder on the end 0 of the plate D, will bind the crossbar tightly to the upper edge of the outer vessel, A, the turn-buckle being so formed that when it is moved in a direction contrary to that pointed out by the arrow it willbe clear of the said shoulder, and the crossbar will be at liberty to be first elevated at one end and then detached from the cleat b.

The cream-can F has at the bottom the usual central pivot adapted to a step, t, secured to the bottom of the outer vessel, and in the bottom of the can itself is a recess for receiving he lower pointed end, h, of the dasher-spindle G. the upper square end of which fits looselyin a square opening, j, in the cross-bar B. The usual inclined arms is project from thedasherspindle, the latter being also provided with arms at m, to which the wooden scraper H is connected in the peculiarmanner described hereinafter.

A cast-iron lid, I, is fitted snugly to, but so as to be easily removed from, the upper end of the cream-can, a stop, 19, on the former being brought into contact with a projection, n, on the latter, so that the cover cannot turn independently of the can. A cog-wheel, J, is secured to the cover I, between which and the wheel is an annular recess, q, so that the said wheel becomes an available handle by which the said cover may be withdrawn from, and readjusted to, the creanrcan. A wheel, K, having teeth adaptedto those of the wheel J, issecured to a spindle, t, having two bearings, one in the cross-bar B and the other in a bracket, to, secured to the under side of the crossbar, above which the spindle is provided with a suitable handle, M.

It will be seen that the wheel K and its spindle are carried by the cross-bar, so that on removing the latter the cream-can will be at liberty, the wheel K coming into gear with the wheel J of the can when the cross-bar is readjusted to its place.

It may here be stated that the easiest way of making the cover is to first cast the wheel and its hub, and then to introduce a portion of the latter into the mold prepared for easting the cover I.

Thepeculiar man nor of connectin g the scraper H to the arms m m of the dasher is shown in the perspective views, Figs. 7 and 8. The 5 lower arm, m, has in the under side a recess for receiving a pivot, to, on a small casting, N, having two wings, the lower end of the scraper H being introduced between these wings, after which the latter are compressed by a suitable instrument, and are thus made to gripe the scraper. A similar casting, N, is similarly attached to the upper end of the scraper, and a pivot, u, on this casting is adapted to a recess in the upper arm, m, of the dasher.

In applying the scraper to the arms the casting N is first secured to the said scraper, and its pivot adjusted to the recess of the arm an, after which the pivot of the casting N is adjusted to the recess of the arm m, and its wings subsequently gripe to the scraper,'or the lower casting may be first griped to the scraper and its pivot adjusted to the recess of the arm m, after which the pivot of the casting N is adjusted to the recess of the arm m, and its wings subsequently griped to the scraper, which in either case is thus pivoted to the dasher without any of the usual pins or rivets.

A very cheap ice-cream freezer may be made in the manner above described, the parts being few in number, easily and economically made, and readily put together, and affording means for the ready adjusting of the can within, and its withdrawal from, the outer vessel.

- The manner of operating the freezer for the purpose of freezing the cream by the rotation of the cream-can in contact with ice contained between it and the outer vessel will be readily understood without explanation.

i I claim as my invention 1. The combination, in an ice-cream freezer, of the vesselA, having a cleat, b, and plate D, with the cross-bar B, adapted at one end to the cleat, and carrying near the opposite end a turn-buckle, E, having a segmental inclined plane, f, adapted to a shoulder on the upper projecting end, 6, of the said plate D, all substantially as described.

2. The combination, in an ice-cream freezer, of the cream-can F, and its cover I, having a cog-wheel, J, with the outer vessel, A, and its detachable cover B, carrying the spindle t and cog-wheel K, all substantially as specified.

3. The combination of the cross-bar B and bracket w, secured to the same, with the wheel K and its spindle if, having one bearing in the cross-bar above the wheel and another bearing in the bracket below the wheel, as set forth.

4. The combination of the dasher-spindle G, the cream-vessel, having a cover, 1, adapted to turn on the said spindle, and having a cogwheel, J, and the outer vessel, having a detachable cross-bar, B, carrying the spindle t and wheel K,.and having an opening for receiving the end of the dasher-spindle and preventing the turning of the same, all as described.

5. The combination of the dasher and its recessed arms m m with the scraper H, and castings N N each having a pivot and two wings for embracing the scraper, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
